Dear users, 

We would like to acknowledge the contribution of CollectionSpy. JaCoP as an open source product has obtained access to a free license. We have been already using this tool for profiling Geost constraint and were able to obtain the insight about our code, which was invaluable in speeding up its execution.  We are still learning the full potential of the tool but we do recommend trying it to improve your understanding of your use of the collections in your software. Even for experts with years of experience in using Java collections this tool can bring better understanding of what is going on in your application as well as confirm some worries concerning improper use of the data structures.  Truly it is a nice tool to spy on your collections ;).

best regards,

Radoslaw Szymanek
